Description

Technical Field

[0001] This invention relates to the field of motor technology, specifically to an energy-saving cooling motor. Background Technology

[0002] A permanent magnet rotor motor is an electric motor that uses permanent magnets as the rotor's magnetic field source. Its core feature is that the rotor uses permanent magnet materials to generate a constant magnetic field, eliminating the need for external current excitation, thus driving the rotor to rotate. In current energy-saving cooling motors, when manually inserting and removing magnets for maintenance, they are affected by surrounding magnets, making it difficult to insert them into the rotor. This affects the efficiency of manual assembly and maintenance, making it difficult to achieve a sliding distribution of magnets to reduce the magnetic force influence of surrounding magnets when inserting a magnet. It is also inconvenient for staff to check the consistency of the magnet's magnetic force. Manual disassembly and testing are tedious, time-consuming, and labor-intensive, and not intuitive. It is also inconvenient to control the rotor's cooling. The rotor is located in the center of the motor, resulting in poor cooling control. Furthermore, it is inconvenient for staff to check the quality of the cooling path, and manually feeling the ventilation by hand is highly dangerous.

[0003] Therefore, we propose an energy-saving cooling motor. Summary of the Invention

[0010] Preferably, the magnet mounting component further includes: a positioning ring, a radial limiting ring, a spacer limiting block, a connecting cover ring, and a push nut. Two positioning rings are sleeved on the rotor shaft, and the two positioning rings are located at both ends of the sliding cylinder.

[0011] Preferably, the sliding magnet component includes: a sliding connecting plate and a positioning groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a heat-dissipating rotor component to achieve internal heat dissipation, improving the quality of cooling during operation, reducing excessive energy loss caused by overheating, enhancing structural cooling quality, and increasing energy efficiency. It dissipates heat from the motor core. Furthermore, the structure uses lightweight fabric strips, allowing staff to easily observe the ventilation direction, preventing undetected blockages and improving structural rationality. This structure eliminates the need for manual airflow sensing, ensuring safety, and the cover prevents ambient wind from interfering with the lightweight fabric strips.

[0016] The use of sliding magnet components in conjunction with magnet mounting components facilitates the inspection and disassembly of rotor magnets by staff. A ring of sliding connecting plates is slidably mounted on the annular groove. When inserting rotor magnets into the sliding connecting plates, as the rotor magnets are gradually inserted into the ring of sliding connecting plates, this structure can first slide the already inserted sliding connecting plates together to facilitate the insertion of the last rotor magnet. This improves the flexibility of inspecting and installing rotor magnets, while also avoiding magnetic interference with the insertion of rotor magnets, making it easier for staff to operate, disassemble, and replace them.

[0017] Using a balancing indicator allows staff to easily understand the magnetic force balance of a full rotation of rotor magnets, improving the quality control of rotor magnets and facilitating maintenance. It eliminates the need for tedious individual testing of the magnetic force balance of each rotor magnet. Magnetic field distortion generates asymmetrical electromagnetic tension, exciting periodic rotor vibration and accompanied by abnormal electromagnetic noise. This vibration is transmitted to the load equipment, potentially causing system resonance and accelerating mechanical fatigue fracture. When the magnetic force of a full rotation of rotor magnets is consistent, it can be observed directly. Attached Figure Description

Two annular grooves 4011 are formed on the sliding cylinder 401. Two sets of positioning bolts 402 are inserted into the sliding cylinder 401, and the two sets of positioning bolts 402 are threaded onto the rotor shaft 201. The magnet mounting component 4 also includes: a positioning ring 403, a radial limiting ring 4031, a spacer limiting block 4032, a connecting cover ring 4033, and a push nut 404.

When inserting the rotor magnets 502 into the sliding connecting plates 501, as the rotor magnets 502 are gradually inserted into the ring of sliding connecting plates 501, this structure allows the already inserted sliding connecting plates 501 to be slid together, facilitating the insertion of the last rotor magnet 502.

[0024] In Example 2, based on Example 1, the equalization indicator 6 includes: an indexing plate 601 and a positioning shaft 602. The indexing plate 601 is fixedly mounted on the positioning ring 403 on the side of the rotor magnet 502 with markings. The indexing plate 601 has graduations. A ring of positioning shafts 602 is slidably inserted into the indexing plate 601, and each ring of positioning shafts 602 is aligned with the markings on a ring of rotor magnets 502. The equalization indicator 6 also includes: anti-detachment springs 603. Anti-detachment springs 603 are respectively sleeved on a ring of positioning shafts 602, and the ends of the ring of anti-detachment springs 603 are respectively connected to the indexing plate 601. The other ends of the ring of anti-detachment springs 603 are respectively connected to the ends of the positioning shafts 602. The equalization indicator 6 makes it easier for workers to understand the magnetic force equalization of a ring of rotor magnets 502. This design can improve the quality control of rotor magnet 502. Due to the influence of high temperature and vibration, rotor magnet 502 may be prone to demagnetization. This structure facilitates maintenance by staff, eliminating the need for tedious individual testing of the magnetic uniformity of rotor magnet 502. Magnetic field distortion generates asymmetrical electromagnetic tension, which excites periodic vibration of the rotor, accompanied by abnormal electromagnetic noise. The vibration is transmitted to the load equipment, which may cause system resonance and accelerate mechanical fatigue fracture. When the magnetic force of one ring of rotor magnet 502 is consistent, with the sliding connecting plate 501, the spacing of one ring of rotor magnet 502 tends to be consistent under the action of magnetic force. By observing the markings at the ends of rotor magnet 502 with the positioning shaft 602 on the indexing plate 601, the uniformity of the distribution of one ring of rotor magnet 502 can be determined.

[0025] The working principle of this embodiment is as follows: First, when inserting the rotor magnet 502 into the sliding connecting plate 501, as the rotor magnet 502 is gradually inserted into one circle of the sliding connecting plate 501, this structure can manually slide the sliding connecting plates 501 that have already had the rotor magnet 502 inserted into them together in the annular groove 4011 on the sliding cylinder 401 to facilitate the insertion of the last rotor magnet 502. After all the rotor magnets 502 have been inserted into one circle of the sliding connecting plate 501, the two push nuts 404 can be tightened respectively, which will drive the interval limit block 4032 to insert into one circle of the sliding connecting plate 501. At the intervals on both sides, two radial limiting rings 4031 are respectively inserted into two positioning grooves 5011 to achieve positioning. During the process, the position can be easily adjusted by manually moving the sliding connecting plate 501 to facilitate the insertion of the interval limiting block 4032. When it is necessary to test the magnetic consistency of the rotor magnet 502, the push nut 404 can be rotated first to pull the interval limiting block 4032 out of the sliding connecting plate 501. At this time, the sliding connecting plate 501 can be elastically attached to the end of the rotor magnet 502 under the pull of the anti-detachment tension spring 603. When the magnetic force is consistent, with the sliding connecting plate 501, the spacing of the rotor magnets 502 tends to be consistent under the magnetic force. By observing the markings at the ends of the rotor magnets 502 with the positioning shaft 602 on the indexing plate 601, the uniformity of the distribution of the rotor magnets 502 can be determined, thus judging the consistency of the magnetic force of the rotor magnets 502. The motor housing 101 has an end cap bolted to its end, consistent with the existing motor housing, which facilitates the disassembly and installation of the rotor shaft 201. As the stator is energized, a magnetic field is generated, which, together with the rotor magnets 502, drives the rotor shaft 201. 1. When rotating, it can drive the impeller blades 202 to rotate, assisting in generating airflow, which is discharged or drawn in from the discharge port 2011. At the same time, when airflow is generated in the rotor shaft 201, it is necessary to test the smoothness of the airflow. The cover 102 is put on the sleeve 1011 for temporary obstruction. At this time, it can be observed whether the swing direction of the lightweight cloth strip 302 is in line with the airflow direction generated in the rotor shaft 201 when the impeller blades 202 rotate. When the lightweight cloth strip 302 flutters in the opposite direction or moves slightly, it indicates that the airflow is smooth and the operation is safe and reliable. Then the cover 102 can be removed to ensure normal ventilation.
